Letters Patent No. 109,849, dated December 6, 1870.

IMPROVEMENT iN BUCKLES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all persons to whom these presents may come:

Be it known that I, GEORGE E. STEDMAN, -of

- Boston, of the county of Suffolk and State of Massiv chusetts, haveinvented a new and useful orlm- Aproved Buckle; and do hereby declarethe same to be fully described in the following specification, andrepresented in the accompanying drawing, in which- Figure l is a topview; Figure 2, a, horizontal section; and

Figure 3 is a longitudinal section of'it as applied to a strap. A

' In this buckle the tongue .is provided with a lockto move with thetongue, and to serve lto fasten the tongue down in the frame to whichsuch tongue may be. pivoted.

In the drawing- A denotes. the buckle-frame, which has within it andpivoted to it, as shdw'n at a a, the box b of a lock, B, from which thebuckle-tongue C projects, and when down in the frame enters a smallrccess,^d, inA the frame..

The box B contains two bolts, c c, connected by a joint-link or lever,f, having its fulcrum at q.

To .one` of the said bolts there is a se't'of ono or more tumblers, 7e,to Operate with a stud, i.

'lhe bolts play through opposite sides of the lock- V case', there beingrecessed] l, made in'tho frame of sense constitutes part of the tongue,the two being movable together withirithe buckile-frame.

On turning the key the boltsvwillbe simultaneously Yshot forward orretracted, as occasion may require,

whether to fastenthe tongue or unfasten it` as circum- 2 stances mayrequire.

The strap'is to be fastened to the end bar m of the f frame. I am awareof the tug-buckle shown in the United States Patent, No. 47,570, suchtug-buckle beingrepresented as having a tongue stationary relativeto the.buekle-frarne, and having to thelatter a pivoted plate or cap providedwith a latch, the object of such plate being to hold -the strap in placeon the tongue. I make no claim tp such tug-buckle.'

Nor do I herein claim a buckle as provided not only with a tonguepivoted to the frame, but with a capplate pivoted to such frame andfurnished with a lock to fasten itdow'n in the frame, such being asshown in a pending application for a patent filed by me on March 31,1869.

My present locking-buckle is much simpler' in con'- struction than thelatter', and is better in many respects. Y

Although I have shown the lock as provided with two boltsv to operate inopposite'directions from it, a lock having a single bolt maybesubstituted; but one with two bolt-s is preferable on account of thebetter support they afford thelock iu the frame.

I make no claim to a'lockingfbu'ckleconstructed in either of the ways"as described in the English patent of Greenwood, dated December 14,1869, wherein the lock is made fast within or to the frame as to beimmovable with respectto it.

In iny buckle, however, the lock is hinged to the frame, and the tongueprojects directly from the lockcase, and is movable with it relativelyto the frame, such changes in the buckle admitting of' a strap beingintroduced aiuldrawn into or out of the frame with f great-er:lfacility.

. I. therefore claim as my invention- The im proved locking-buckle,having its lock-case piroted tothe frame and the tongue projected fromthe said case and movable withit, as described.
